Definitions

  • the present invention relates to an infrared lamp with a substantially trough-shaped luminaire housing for receiving an infrared light source, in which an end-side beam outlet opening is recessed, and a stand connected to the lamp housing.
  • Such infrared lamps which are also called red light lamps due to the red light filters, which are typically provided with a visible light blocking filter, are known in the art, and are preferably used for medical heat or infrared therapy.
  • the heat radiation emitted by the infrared lights can penetrate deep into the tissue and muscles and, due to the associated vasodilatory effect, promotes the circulation of the irradiated area.
  • Infrared therapy is particularly beneficial in pain relief, particularly in relieving muscle tension and muscle spasms, and in speeding healing of inflammatory processes such as sinusitis. Also in the therapeutic and cosmetic treatment of the skin, the irradiation with infrared light is successfully used.
  • infrared light sources electric light sources are used, which have the highest possible proportion of infrared.
  • the light emitted in the visible spectral range is often absorbed by suitable filters and thus also converted into heat.
  • the typically used infrared light sources are usually mirrored and designed so that a large part of the heat radiation generated can be emitted via the frontal radiation outlet opening of the lamp housing, heating of the lamp housing is practically unavoidable even during operation. This considerably complicates the setting and handling of the already in operation infrared lamp by the user.
  • the present invention is therefore based on the technical problem of specifying an infrared lamp of the type described above, which is easy and convenient to handle even during operation and can be easily reoriented by the user even with prolonged operation, without the user hot Surfaces of the lamp housing comes into contact.
  • the invention proposes to form the luminaire housing at least in a partial area double-walled, wherein between the two walls of the housing, a heat-insulating air layer is present.
  • the invention accordingly an infrared lamp with a substantially trough-shaped luminaire housing for receiving an infrared light source, in which an end-side beam outlet opening is recessed, and a stand connected to the lamp housing, which is characterized in that the lamp housing is at least partially surrounded by a protective sheath, wherein between an outer surface of the lamp housing and an inner surface of the protective jacket serving as a heat insulator air gap is defined.
  • the outer protective jacket is significantly cooler even after prolonged use than the inner lamp housing itself. The user can therefore easily grab the infrared lamp on the protective jacket and set and align according to his wishes.
  • the cooling effect is favored if, as provided in a preferred embodiment of the infrared lamp according to the invention, a plurality of openings are recessed in the protective jacket, can escape through the heated air from the air gap and cool air from the environment can penetrate into the air gap.
  • a conveyor for example, an electrically operated fan.
  • Such home-use infrared lamps usually have a small base which has a height which allows the lamp to be conveniently placed on a table.
  • the light is then usually oriented slightly upwards to irradiate, for example, the facial area of the user. Therefore, it is advantageous, on the one hand, to arrange openings in the end-side end region of the protective jacket, through which the rising heated air can escape from the air gap into the environment.
  • these first exit openings may be configured as substantially axially oriented, i. be formed substantially parallel to the longitudinal axis of the lamp extending slots which are recessed on the periphery of the front end portion of the protective jacket.
  • a second group of openings in a section of the protective jacket facing away from the end-side end region, through which cooler air from the surroundings can penetrate into the air gap.
  • the second openings for example, oriented radially to the longitudinal axis of the infrared lamp and be recessed in a rear end portion of a likewise trough-shaped protective jacket. Due to the interaction of the first and second openings, an effective and permanent cooling is effected during operation of the infrared lamp due to the chimney effect resulting from the heating of the air in the air gap, so that the protective jacket does not or only slightly heats up even during prolonged operation.
  • the first and second openings are preferably distributed substantially uniformly around the longitudinal axis of the luminaire.
  • the protective jacket is preferably made of a material with low thermal conductivity, for example a plastic material. Particularly advantageous is the protective jacket of a transparent material, such as polycarbonate.
  • the lamp housing is pivotally hinged to the base.
  • the base for example have a U-shaped carrier, the two arms engage through two of the first axially oriented, slot-shaped openings of the protective jacket and are pivotally mounted on a hinge of the lamp housing.
  • the infrared lamp according to the invention has a mechanical or electrical timer, which makes it possible to set the duration of treatment, for example, according to a treatment period prescribed by a doctor.
  • the timer is designed as a rotary switch.
  • the timer can also include a numerical display, which represents the set total treatment time in luminous numbers, for example in the form of a 7-segment display.
  • the setting of the total treatment time can in turn be done via a knob or push buttons, with which the treatment time is extended or shortened by a fixed value, for example, each time the push button.
  • the display may indicate the total treatment duration and / or, during operation, the remaining treatment time. It can also be provided, for example, a push button with which can be switched back and forth between the total treatment time and the remaining treatment time.
  • LEDs light emitting diodes
  • FIG. 1 shows an infrared lamp, generally designated by the reference numeral 10, which has a substantially trough-shaped luminaire housing 11 in which an infrared light source (not shown in the figures for better clarity) can be mounted.
  • the infrared light usually known electrical connection means for supplying the infrared light source with electrical energy.
  • a screw socket (not shown) can be arranged, into which the infrared light source can be screwed with its lamp base, which allows convenient replacement of the infrared light source in the event of a defect.
  • an opening 14 is recessed, through which the infrared light source can be installed in the housing.
  • the opening 14 also serves as an outlet opening for the infrared radiation of the infrared light source.
  • the luminaire housing 11 is mounted on a pedestal 15, the underside 16 of which is coated with a non-slip support, for example a rubber surface.
  • the base 15 has a U-shaped support 17, the two arms 18, 19 (not shown in more detail here) pivot joints of the lamp housing 11 are pivotally mounted (see in particular also the rear view of Figure 3).
  • the lamp housing 11 is surrounded by a likewise substantially trough-shaped protective jacket 20. Between the outer surface 21 of the lamp housing 11 and the inner surface 22 of the protective jacket 20 serving as a heat insulator air gap 23 is defined.
  • the protective jacket 20 consists of two different materials.
  • the protective jacket 20 of the lamp housing 11 is continued as an L-shaped folded-back portion 24.
  • the L-shaped folded-back portion 24 therefore forms a surrounding the outlet opening 14 ring.
  • a section 25 of the protective sheath 20 of transparent material adjoins the portion L which is folded back in an L-shaped manner.
  • the section 25 has a perpendicular to the longitudinal axis of the infrared light 10 oriented end portion 26, which restores the connection with the lamp housing 11 in the rear portion of the lamp.
  • slit-like openings 27 oriented substantially parallel to the longitudinal axis of the infrared lamp are recessed, through which hot air can escape from the air gap 23 into the environment.
  • openings 28 which are oriented radially relative to the longitudinal axis are recessed, through which cool air can flow from the outside into the air gap 23. The resulting chimney effect causes effective cooling of the infrared lamp according to the invention.
  • the reference numeral 29 indicates a arranged at the foot 15 of the infrared light 10 timer.
  • the timer is shown schematically as a rotary switch 29, which allows the adjustment of the total treatment time.
  • the rotary switch for example, have a latching zero position, so that with the setting of the treatment time, the switching on and off of the infrared light can be effected.
  • Figure 4 shows a variant of the foot 15 'of the infrared light of Figure 1 in an enlarged sectional view, wherein the lamp itself is not shown.
  • the timer 30 has a numerical display 31 with 7-segment display for displaying the set total treatment time and an existing multi-light emitting diode LED bar 32 for displaying the Rest treatment duration on.
  • two pressure switches 33 and 34 are provided for switching on and off the infrared light above the display 31, while pressure switches 35 and 36 serve to reduce the total treatment duration shown in the numeric display 31 by multiple actuation (pressure switch 35) or to enlarge (pressure switch 36).
  • the total treatment duration is always displayed in the numerical display 31, while during operation the number of LEDs illuminating in the LED strip 32 is proportional to the instantaneous remaining treatment duration.
  • the user always receives an indication of the remaining treatment time.
  • the numerical display 31 is switchable between the total treatment time and the current residual treatment time or even toggles at predetermined intervals between the two time displays.
